The Ephraim Hawley House is a privately owned Colonial American wooden post-and-beam timber-frame saltbox house situated on the Farm Highway, Route 108, on the south side of Mischa Hill, in Nichols, a village located within the town of Trumbull, Connecticut, the U.S.[1] It was expanded to its present shape by three additions.

[2][3][4] Over time, the location of the house has been identified in four different named townships, as jurisdictional boundaries changed, but it has never been moved.

The Hawley Homestead was dated to 1690 during the Works Progress Administration Federal Writers' Project conducted during the Great Depression.

Joan Oppenheim created a research report on the house while studying at the Yale School of Fine Arts in the 1930s.

The roof sheathing and flooring is vertically quarter sawn, one-inch-thick oak boards with random widths between twelve and thirty inches.

A forty-inch deep brick beehive oven is built into the right rear wall of the kitchen fireplace and its opening has a wrought iron lintel.

The ceilings and walls are plaster, made up of calcined oyster shells with red cattle hair.

The plaster was applied on riven oak lath attached with small hand wrought iron nails.

[11] McKee [12] writes about a Massachusetts contract dating to 1675 that specified the plasterer, “Is to lath and siele (seal)[13] the four rooms of the house betwixt (between) the joists overhead with a coat of lime and hair upon the clay; also to fill the gable ends of the house with ricks (bricks) and plaster them with clay.

The said Daniel Andrews is to find lime, bricks, clay, stone, hair, together with laborers and workmen… .”[14] Records of the New Haven colony mention rates for plaster and lath as early as 1641.

When the lean-to was built, the roof was extended, without a break, to within six feet six inches of the ground and gave the house its saltbox shape.

[16] In October 1882, Bradley sold the house to his neighbor Clarissa Curtis for $525 ($175 cash, and Curtiss assumed the $350 mortgage to Fairchild).

[17] On December 7, 1696, the Farm Highway, present-day Nichols Avenue Connecticut Route 108, was laid out by the Stratford selectmen to the south side of Mischa Hill.

[18] The highway was 12 rods wide, or 198 feet, where Broadbridge Brook runs off the south side of Mischa Hill, at the Zachariah Curtiss house, his land, and at Captain's Farm.

The Hawley house was also featured on the cover of the first modern street map of the town of Trumbull, published in 1965.
